End-of-life notice: American Legal Ethics Library
As of March 1, 2013, the Legal Information Institute is no longer maintaining the information in the American Legal Ethics Library. It is no longer possible for us to maintain it at a level of completeness and accuracy given its staffing needs. It is very possible that we will revive it at a future time. At this point, it is in need of a complete technological renovation and reworking of the "correspondent firm" model which successfully sustained it for many years.
Many people have contributed time and effort to the project over the years, and we would like to thank them. In particular, Roger Cramton and Peter Martin not only conceived ALEL but gave much of their own labor to it. We are also grateful to Brad Wendel for his editorial contributions, to Brian Toohey and all at Jones Day for their efforts, and to all of our correspondents and contributors. Thank you.
We regret any inconvenience.
Some portions of the collection may already be severely out of date, so please be cautious in your use of this material.
Arizona Rules of Professional Conduct
Comment - ER 1.18
 Prospective clients, like clients, may disclose information to a lawyer, place documents or other property in the lawyer's custody, or rely on the lawyer's advice. A lawyer's discussions with a prospective client usually are limited in time and depth and leave both the prospective client and the lawyer free (and sometimes required) to proceed no further. Hence, prospective clients should receive some but not all of the protection afforded clients.
 Not all persons who communicate information to a lawyer are entitled to protection under this Rule. A person who communicates information unilaterally to a lawyer is not a ˛prospective clientÓ within the meaning of paragraph (a) and, therefore, the information does not subject the lawyer to disqualification under this Rule. Lawyers should employ reasonable measures to alert prospective clients that a) they should not convey information about a legal matter unilaterally to the lawyer and b) unilateral communications may not be kept confidential.
 It is often necessary for a prospective client to reveal information to the lawyer during an initial consultation prior to the decision about formation of a client-lawyer relationship. The lawyer often must learn such information to determine whether there is a conflict of interest with an existing client and whether the matter is one that the lawyer is willing to undertake. Paragraph (b) prohibits the lawyer from using or revealing that information, except as permitted by ER 1.9, even if the client or lawyer decides not to proceed with the representation. The duty exists regardless of how brief the initial conference may be.
 Any information obtained from a prospective client who consults the lawyer in an attempt to disqualify the lawyer or make contact for some purpose other than seeking representation is not information relating to representation and disclosure is not prohibited.
 In order to avoid acquiring disqualifying information from a prospective client, a lawyer considering whether or not to undertake a new matter should limit the initial interview to only such information as reasonably appears necessary for that purpose. Where the information indicates that a conflict of interest or other reason for non-representation exists, the lawyer should so inform the prospective client or decline the representation. If the prospective client wishes to retain the lawyer, and if consent is possible under ER 1.7, then consent from all affected present or former clients must be obtained before accepting the representation.
 A lawyer may condition conversations with a prospective client on the person's informed consent that no information disclosed during the consultation will prohibit the lawyer from representing a different client in the matter. See ER 1.0(e) for the definition of informed consent. If the agreement expressly so provides, the prospective client may also consent to the lawyer's subsequent use of information received from the prospective client.
 Even in the absence of an agreement, under paragraph (c), the lawyer is not prohibited from representing a client with interests adverse to those of the prospective client in the same or a substantially related matter unless the lawyer has received from the prospective client information that could be significantly harmful if used in the matter.
 Under paragraph (c), the prohibition in this Rule is imputed to other lawyers as provided in ER 1.10, but, under paragraph (d), imputation may be avoided if the lawyer obtains the informed consent, confirmed in writing, of both the prospective and affected clients. In the alternative, imputation may be avoided if all disqualified lawyers are timely screened and written notice is promptly given to the prospective client. See ER 1.0(k) (requirements for screening procedures). Paragraph (d)(1) does not prohibit the screened lawyer from receiving a salary or partnership share established by prior independent agreement, but that lawyer may not receive compensation directly related to the matter in which the lawyer is disqualified.
 Notice, including a description of the screened lawyer's prior representation and of the screening procedures employed, generally should be given as soon as practicable after the need for screening becomes apparent. When disclosure is likely to significantly injure the client, a reasonable delay may be justified.
 For the duty of competence of a lawyer who gives assistance on the merits of a matter to a prospective client, see ER 1.1. For a lawyer's duties when a prospective client entrusts valuables or papers to the lawyer's care, see ER 1.15.
